//******************************************************************************************
// File: S_TimedRelay_MCP.h
// Authors: Dan G Ogorchock
//
// Summary: S_TimedRelay_MCP is a class which implements the SmartThings "Relay" device capability. It features
// an automatic-turn-off time delay for a relay to emulate a button press.
//
// It inherits from the st::Sensor class and clones much from the st::Executor Class
//
// Create an instance of this class in your sketch's global variable section
// For Example: st::S_TimedRelay_MCP sensor1(F("relaySwitch1"), PIN_RELAY, LOW, true, 1000, 0, 1, 0);
//
// st::S_TimedRelay_MCP() constructor requires the following arguments
// - String &name - REQUIRED - the name of the object - must match the Groovy ST_Anything DeviceType tile name
// - byte pinOutput - REQUIRED - the Arduino Pin to be used as a digital output
// - bool startingState - REQUIRED - the value desired for the initial state of the switch. LOW = "off", HIGH = "on"
// - bool invertLogic - REQUIRED - determines whether the Arduino Digital Ouput should use inverted logic
// - long onTime - REQUIRED - the number of milliseconds to keep the output on, DEFGAULTS to 1000 milliseconds
// - long offTime - OPTIONAL - the number of milliseconds to keep the output off, DEFAULTS to 0
// - int numCycles - OPTIONAL - the number of times to repeat the on/off cycle, DEFAULTS to 1
// - byte finalState - OPTIONAL - leave in X state after finishing sequence 0 = off, 1 = on , Defaults to 0
//
// Change History:

// Date Who What
// ---- --- ----
// 2015-12-29 Dan Ogorchock Original Creation
// 2018-08-30 Dan Ogorchock Modified comment section above to comply with new Parent/Child Device Handler requirements
// 2019-06-23 Brian Wilson Added finalState option
// 2019-08-10 Dan Ogorchock Added public getStatus()
// 2020-08-17 M2_ Modified for MCP23008. Only change was file name and class name.
